What are context managers in async Python?

Context managers in async Python are used to manage resources, ensuring proper setup and teardown in asynchronous code.

Can you give me an example of how to use a context manager in an async function?

Sure! Here's a simple example:

import asyncio

class AsyncContextManager:
    async def __aenter__(self):
        print('Entering the context')
        return self

    async def __aexit__(self, exc_type, exc_val, exc_tb):
        print('Exiting the context')

async def main():
    async with AsyncContextManager():
        print('Inside the context')

asyncio.run(main())

What happens if an exception occurs inside the context manager?

If an exception occurs, the __aexit__ method is still called, allowing you to handle the exception gracefully.
